We are not within sight of the grand Causse Méjean, nor of the Black Causse, or Causse Noir, and only on the threshold of Sauveterre, yet some idea may be gathered here of what M. E. Réclus calls a 'Jurassic archipelago,' once a vast Jurassic island. Imagine, then, a group of promontories, their area equal to that of Salisbury Plain, Dartmoor and Exmoor combined, with the varying altitudes of the loftiest Devonshire tor and Cumberland hill. Such a comparison may convey some feeble notion of the three Causses just named, two of which belong to the Lozère. The Causse Noir is partly in the Aveyron. Their extraordinary conformation must be seen and studied by all who would familiarize themselves with this geological phenomenon. No solitude can be more complete than these wastes, except when a leaden sky replaces the warm sunshine of to-day, and a deep, impenetrable mantle of snow covers the plateau from end to end. Then the little life that animates it is hushed, and none from the outer world penetrates the fastnesses of the Causses. We drive on for a mile or two till we reach the summit of the plateau. Here, at a height of 2,952 feet above the sea-level, is a ruined château turned into a farmhouse, where we rest our horses a little and prepare to make tea. The farmer's wife and two children come out to chat with our driver and look at us, evidently welcoming such a distraction. And no wonder! I brought out our bonbon box--one must never take a drive in France unprovided with sweetmeats--and tried to tame the children; but they clung to mother's skirts, and only consented to have the bonbons popped into their mouths, with faces shyly hidden in her apron. 'Would you like a cup of tea?' I asked. But madame shook her head, giggling, and I do not suppose ever heard of such an infusion in her life. Meantime, tea-making on that breezy eminence was no easy matter. The little flames of my spirit-lamp were blown hither and thither--anywhere but in the right direction. At last our excellent driver, resourceful as a true son of Gaul is bound to be, lifted up the tiny machine, all afire as it was, and thrust it into that convenient box behind the calèche all travellers know of. The good man burnt his fingers, but had the satisfaction of making the water boil, and there for the first time, without doubt, tea was made after the English fashion. No place could be better adapted for a holiday resort. In summer these sweeps are one gorgeous mosaic of wild-flowers, and the short stunted grass shoots up, making verdure everywhere.
